 Students will be able to describe a frog
habitat.

Egg Stage 1

Frogs are amphibians, which means
that they can live on land and in the
water. Frogs begin their life cycle in
the water. Female frogs can lay as
many as 6,000 eggs in clumps called
spawn. Each egg is a ball of jelly. The
spawn floats to the top of the pond
where the water is warmer and helps
the eggs to grow.
Tadpole-Stage 2

After about 10 days
the tadpole is ready
to wiggle from the
egg. Tadpoles
breathe through
gills on the outside
of their bodies for
about 5 weeks.
Tadpole-Stage 3

The back legs
begin to appear
and its outside gills
begin to disappear.
It can still breathe
underwater through
gills which are
inside of its body.
Tadpole-Stage 4

About 1 week after
the legs have
appeared the
tadpole will begin to
develop lungs and
then breathes air
like us. This means
he now needs to
come to the surface
for air.
Tadpole-Stage 5

At about 10 weeks
the tadpole
develops front legs
and will not need to
eat as it will start to
absorb its tail and
get food from the
nutrients that are in
it.
Froglet to Frog


After about 3 ½ months the tadpole has
become a froglet and is ready to eat small
bugs and spend time out of the water.
The frog continues to grow, it loses its tail
completely and leaves the pond. The frog
will eat crickets and other insects, bugs, and
worms. Frogs need to live in damp places.
